Embodiment Construction

[0023] In order to make the technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0024] refer to figure 1 , the present embodiment provides a networked redundant aircraft control system. The present invention connects multiple sets of similar or non-similar flight control computers to the network through the communication equipment in the system, and performs control commands through the arbitration unit on the network. Comparison and decision-making, select the appropriate instruction for output. In addition, in order to realize the supervision and redundant processing of the arbitration unit, the system includes a channel selection unit connecting the main flight control computer a...

Abstract

The invention provides a networked redundancy aircraft control system, and belongs to the technical field of aircraft control. According to the networked redundancy aircraft control system, multiple sets of similar or non-similar flight control computers are connected through a network by means of communication equipment in the system, comparison and decision making of control instructions are conducted by means of an arbitration unit on the network, and the appropriate instructions are selected to be output. In addition, in order to achieve supervision and redundancy processing of the arbitration unit, the system comprises a channel selection unit connected with the main flight control computer and the arbitration unit, the health states of the two units are judged according to heartbeatsignals of the arbitration unit and the main flight control computer, the reasonable instructions are selected according to the judgment result to control corresponding execution mechanisms, and meanwhile the units which work abnormally are reset. The networked redundancy aircraft control system can effectively improve the reliability and redundancy of the system.

Description

technical field [0001] The invention belongs to the technical field of aircraft control, and in particular relates to an aircraft control system with network redundancy. Background technique [0002] The basic function of the aircraft control system is to ensure the stable attitude of the aircraft through a certain control algorithm according to certain index requirements, and guide the aircraft to the desired position through a given control strategy to complete the established flight mission. At the same time, during the flight, the information exchange between the aircraft and the ground control station is realized. [0003] At present, the aircraft control systems on the market are mainly aimed at the single-redundancy control of a single aircraft, which can better meet the installation and use requirements of small aircraft. However, for aircraft carrying high-cost reconnaissance / surveillance payloads, or even large and medium-sized aircraft that integrate reconnaissan...
